[Elecraft] XG3 question

[Edward R. Cole]

Jim,

Kurt is correct (I will expand on his suggestion).

First you should find the center frequency of your radio (72.9 
MHz).  ON the main window of the XG3 Utility Press window 2 and then 
Press "edit".  Enter the center freq. in the window labeled 
2.    Press "Apply" and then "OK".   The freq that you found that 
quieted the radio will be shown as current freq. at the window at the 
top. The XG3 outputs a carrier which will quiet an FM radio when the 
signal is strong enough.  Set output level to -73 dBm should work or 
use -33 dBm.  I found I could radiate enough -33 dBm signal with a 
rubber duckie antenna connected to the XG3 place near my 2m FM radio 
for it to pick up the signal.

Once you know that enter a frequency offset from that until the radio 
is no longer quiet.  Use these two frequencies in the scan window 
(PRESS the edit sweeps button).  Enter the first freq in the "Start 
Freq" window and the second freq in the  "Stop Freq" window.  Enter 
.005 for Step Freq then Enter 100 (ms) in the Step Time 
window.  Check "Repeat" and "OK".

ON the main window of the XG3 Utility Press PF1 or PF2 depending on 
which you set up and the XG3 will begin to rapidly step in freq and 
you should hear it go from a fully quiet to a noisy signal to full 
noise and you will hear a "pop-pop-pop" as the XG3 scans.

Jim,

      To add to what Mike said in the reflector, and, as I understand it,
you can make the XG3 scan between two set frequencies. I suspect that,
if you set those frequencies fairly narrow and within the band pass of
the receiver, you should get some buzz (I suspect some sort of
saw-tooth). Of course, I don't know how fast it would scan, but I would
think that you should be able to detect it. Hope that helps until
someone with hands-on experience can reply...
